Abstract
An energy conservation control device of a multi-path collecting and drying room is characterized in that a sensor temperature module of the drying room is connected with the input end of a single-chip computer CPU; and the output end of the single-chip computer CPU is connected with a voltage output control circuit by a D/A conversion module. The energy conservation control device has the beneficial effects that by practical application of wood drying, the energy conservation ratio is between 53 percent and 66 percent when the drying cycle is not prolonged, the quality of dried products is greatly improved, with little cracking, and the deformation of the dried products is greatly decreased.
Description
Technical field
The utility model belongs to the wood processing technique field, relates to a kind of improvement of lumber kiln control device.
Background technology
The current drying technology is in the general just application of a lot of industries.But generally all be to adopt the fixedly mode of heating of air quantity, wind speed.This drying system is example with the drying of wood, and main existing problems are the thing surface sclerosis easily that are dried, and hydrone moves obstructed from inside to outside, easily causes end face cracking, the composition deformation amount that is dried big, produces great energy waste simultaneously.The manual control energy-saving and frequency-variable controller of market appearance in recent years, though can save a part of electric energy, but in dry run, to operate control at any time by operating personnel according to each stage of drying, not only operating personnel are had relatively high expectations, the drying curve jumping characteristic is big simultaneously, and dry run can not be fully rationally.
Summary of the invention
The purpose of this utility model is: a kind of multi pass acquisition hothouse energy-saving control device is provided, but its low power consuming, dry in high quality required dry thing.
The technical solution of the utility model is: the sensor temperature module of hothouse is connected with the singlechip CPU input, and the singlechip CPU output is connected with voltage output control circuit by the D/A modular converter.
Clock-pulse generator also is connected with voltage output control circuit, and the output of power voltage connects the electric power blower fan by frequency converter.
The beneficial effects of the utility model are: by the application in practice to the drying of wood, when not prolonging arid cycle, the economize on electricity ratio is between 53% ~ 66%, and dry product quality increases substantially, substantially do not have cracking phenomena, dry product deflection significantly reduces.
Description of drawings
Fig. 1 is the utility model schematic block circuit diagram;
Fig. 2 is the utility model circuit diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 2, R is that resistance, C are that electric capacity, U3 are that singlechip CPU, U5 are that D/A modular converter, U4 are signal amplifiers.
In the starting stage of drying operation, the signal of sensor output is strong, provides one by the CPU processing and controls analog signal more by force, the frequency converter output frequency is just high, the rotation speed of fan height, the air quantity wind speed is bigger, and firing rate is fast, along with dry run is progressively carried out, the signal of sensor output progressively reduces, and the analog signal of handling back output by CPU also progressively reduces simultaneously, and the frequency converter output frequency also progressively reduces, blower fan is in the low-frequency operation state, and heat supply and air quantity wind speed also progressively reduce.Make dry run more reasonable, can also save a large amount of energy simultaneously.
In dry run according to the fundamental of drying principles, to reasonably select heat carrier and evaporation wind speed, wind speed is crossed the surface sclerosis that conference causes the thing that is dried, hydrone is not easy to move to outer surface, the composition deformation that is dried strengthens, cracking phenomena is serious, otherwise the thing superficial water molecule that is dried is not easy evaporation.
For remedying the deficiency of motor airflow pressure and heat supply when the low-frequency operation, the pulse air quantity controller can be in whole dry run, export the pulse control signal of a certain width at set intervals, intermittently improve the air quantity wind speed, the hydrone that the extremely dry from inside to outside thing of the thing surface that is dried is moved is able to rapid evaporation.
At first by the humidity module 3223 perception ambient humidities in hothouse, the humidity data with perception is transferred to single-chip microcomputer to this utility model simultaneously; Single-chip microcomputer carries out calculation process with resulting multichannel humidity data, and according to the preplaced line sexual intercourse, humidity data is converted to corresponding frequencies, is transferred to the D/A modular converter afterwards; The D/A modular converter is converted to corresponding analog signal to the gained data signal, and the control frequency converter; Clock-pulse generator produces the pulse simulation voltage signal of specific period and sends frequency converter to by initialize data simultaneously; Frequency converter is controlled motor speed to realize transferring in real time the purpose of number according to the analog signal that is received.So this utility model can realize control in real time, and can carry out drying with optimal curve, the while is energy savings to greatest extent.
Clock-pulse generator produces the pulse simulation voltage signal of specific period and sends frequency converter to by initialize data; Frequency converter can be realized controlling motor speed with specific period by CF according to the signal of the clock-pulse generator that is received.Defective with compensation dry run later stage air quantity, shortage of heat.
